BEER AND HOP S EPARATOR.

Patented Aug. 11, 1914:.

Application filed November 13, 1913. Serial No. 800,822

To all whom it may concern I Be it known that I, MAX RICHARD Inn- GANG, a citizen of the United States of -America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Beer and Hop Separators, of which the followingis a specification.

The objects of this invention are to provide improvements in separators adaptedfor use in separating hops or the like from beer, and in compressing the hops for the purpose of removing all liquid therefrom and returning more or less of theliquid to the beer and by this means, to some extent control the flavor of the beer.

A further object of the invention is to provide an improved apparatus adapted to speedily remove the liquid fromthe hops so that the latter may be burned with little, if any, preliminary drying.

An illustrative embodiment ofthe above invention is shown in the accompanying drawings, in which,-Figure 1 is a longitudinal sectional view of aseparator constructed according to this invention. Fig. 2

is atransversesection taken on the line B-B of Fig. 1. Fig. 3 is a sectional view taken on the line CC of Fig. 1. 1

in general, the apparatus comprises a brass wire screen or perforated drum for receiving the beer and hops to be separated,

this drun being provided with perforated blades on its interiorysurface adapted to lift hops from the beer in the bottom of the drum and deposit the hops into a spiral conveyer, which in turn delivers the hops to a pair of crushing rollers adapted to extract the remaining liquid from the hops and return any desired quantity of said liquid to the beer which has been separated from the hops; The cylindrical screen is surrounded by an unperforated cylindrical vat from which the separated beer may be drawn after passing through the separating screen into said vat. The apparatus includes a pneumatic means whereby fine jets of air are caused. to pass through the upper portion. of the screen for the purpose of removing the adhering hop leaves and causing them to drop into. the spiral conveyer.

Referring to the-drawings, the supporting frames 1 and 2 support a non-rotating cylindrical receptacle 3, which receives the .ings working its way into the beer.

separated beer. This receptacle is provided wlth an outlet 4, having a suitable valve 5 to permit the separated beer to be drawn therefrom as desired.

The receptacle 3 carries two pairs of stub shafts 6 and 7 on which are journaled rollers 8 and 9 in engagement with grooved wheels 10 and 11 fast to annular flanges 12 and 13 integral with the end pieces 14 and 15 of a cylindrical brass separating screen 16 In this manner, the separating screen is rotatably mounted in. the receptacle 3 which receives the separated beer, while the bearings are so arranged that there is little, if any, possibility of lubricant from bear- The screen 16 is rotated by a drive shaft 17 journaled in frames 2 and 18 and receiving power by a belt through the pulley 19 which it carries. Shaft 17 also carries a sprocket wheel 20 connected by a chain 21 wit-h a sprocket wheel 22 fast to flange 1.3. Drive shaftl'? through a chain and sprocket connection 23 drives the shaft 24: of a spiral conveyer 25 extending axially through the separator and journaled at one end in frame and supported in frame 29. Shaft 17 also carries a sprocket connected by a chain 31 with one of a pairof crushing rollers 32 and 33 preferably covered with vulcanite and locatedat the discharge end of a perforated trough 34 through which the conveyer 25 drives the separated hops.

The conveyer shaft 24 carries fast at its free end a pulley 35 connected by a belt 36 with a pulley 37 fast to the shaft of a blower or fan 38. The outlet of the blower 38 comprises a vertical pipe 39 communicating with a perforated pipe 40 extending along the entire length. of the separating screen 16 between it and the surrounding receptacle 3 above the conveyer 25. The interior of the separator16 is provided with a plurality of perforated longitudinal flanges 41 adapted upon rotation of the separator to lift hops out of the beer in the bottom of the separator and deposit the same in the trough 34 of the conveyer. The perforations in the flanges permit beer to drain therefrom without carrying with it the hops before the latter are in position to be deposited in the conveyer. Air discharged from the perforated pipe 40 removes hops adhering to the interior of screen 16 and the surface of in position to receive the hops after the latter have passed between rollers 32 and 33.

The liquid compressed from these rollers.

pours into a trough 43 below rollers 32 and from this trough passes through the pipe 44 into the receptacle 3. A two way valve 45 is provided in pipe 44 so that any part of the liquid removed from the hops by rollers 32 and 33 may be prevented from returning to -receptacle 3.

l-n Fig. l, a gage 46 is shown arranged to disclose the helght of the beer in the receptacle f3 and separator 16.

' In operation, the beer and hops to be separated enter the device through pipe27, and the beer passes through screen 16 into receptacle 3. Rotation of screen 16 carries the hops which have settled in" the bottom of the screen upwardly, depositing them into the conveyer 25. As the screen rotates past periforated pipe 40*, it is cleared of adhering hops by the jets of air from this pipe passing through the screen. The conveyor 25 discharges the separated hops on the rollers 32 and 33 which are continually rotating toward each other at their upper sides and thereby compress the hops, removing liquid therefrom which is delivered into trough 43, while the hops are discharged through chute 42. Part or all of the liquid compressed from the hops passes from pipe 44 into re ceptacl-e 3. By delivering more or less of the juices compressed from the hops, the flavor of the beer may in this manner be much under the control of the operator and require less boiling of the beer and hops previous to their separation.

Although but one specific embodiment of this invention has been hereinshown and described, it will be understood that numerous details of the constructionshown may .be altered or omitted without departing from the spirit of thisinvention as defined by the following claims.

I claim:

1. In a device of the class described, the combination with afiltering device comprlsing a rotary screen having perforated blades for removing semi-solid matter from the bottom of saidscreen, and a receptacle for collecting filtered liquid, of a conveyerqfor removing semi-solid matter from said filtering device, means for expressing liquid from said semi-solid matter, and 'a connection "between said means a'nd'receptacle iior delivering to said receptacle liquid expressed from said semi-solid matter, said connection in cluding a two way valvewhereby any desired portion of the liquid passing through said connection may be tering said receptacle. 1

2. In a device of the class described, the combination with a filtering device comprising a rotary screen having perforated blades for removing semi-solid matter from the bottom of said screenyand adevice for expressing juices froin said semiesolidmatter and returning the juices to the filtering device.
